Question

What is meant by saying a particular gene is dimorphic? A. The gene is present in all individuals of a population B. The gene is present in 50% of a population C. The gene can be found in two different variations D. The gene is present in some individuals, but not found in other individuals In lab we discussed how the Alu gene can be found on both chromosomes of a particular individual. This would be the: A. Homozygous (+/+) condition B. Homozygous (+/-) condition C. Homozygous (-/-) condition D. Heterozygous (+/-) condition The major and minor groove of the DNA helix is important for: A. Catalyzing enzymatic reactions B. How proteins interact with the DNA strand C. How the DNA molecule fits into the nucleus D. How the DNA molecule unwinds for replication The addition of nucleotides to the growing DNA strand is catalyzed by an enzyme called: A. RNA Polymerase B. Ligase C. DNA Polymerase D. Helicase During DNA replication, the enzyme helicase is involved with: A. Unwinding the double-stranded DNA B. Lowering stress placed on the double-stranded DNA C. Keeping the DNA single-stranded so replication is more efficient D. Keeping the template strand as close to the newly synthesized strand as possible Microtubules and microfilaments are said to be "dynamic" elements of the cytoskeleton. In this case, "dynamic" means that: A. Once individual microfilaments and microtubules have formed, they can change shape and move around inside the cell B. They are constantly changing and never in the sample place for very long C. Microtubules and microfilaments are assembled and disassembled and then reassembled again in a regulated manner Which of the following is a major difference between integrins and cadherins? A. Integrins are integral membrane proteins, whereas cadherins are not B. Cadherins are found in cellular junctions, whereas integrins are not C. Integrins allow cells to adhere to the extracellular matrix, whereas cadherins do not D. Cadherins associate with intermediate filaments, whereas integrins do not A new nucleotide can only be added to the _____ end of a growing DNA strand, DNA therefore always grows in the _____ direction A. 3': 5' to 3' B. 5';5' to 3' C. 3': 3' to 5' D. 5', 3'to 5'

Explanation / Answer

21) Dimorphic genes are defined as the presence of two different variants of the gene in the same individual. Therefore, the answer for this question is option C.

22) If the gene is present in both the chromosomes of a particular individual, then the individual is said to be homozygous (+,+) for that particular gene. So, the answer for this question is option A.

23) The major and minor groove in the DNA molecule is important for protein interaction (option B).

24) The addition of nucleotides to the growing end of DNA strand is catalysed by the enzyme DNA polymerase (option C).

25) The function of enzyme DNA helicase is to unwind the DNA double strand (option A).
